Roku, which has shipped more than 10 million devices in the U.S., noted that the move comes after it discontinued software and channel updates on those older players on May 30, 2015.

“HBO strives to offer its customers the best possible experience on the Roku platform,” Roku explained. “Due to Roku’s discontinued support of the classic Roku players, HBO would be unable to guarantee a great video experience on these Classic Roku devices.”

HBO Go still supports the Roku 1 model and above.

To soften the blow, Roku is offering a discount (20%, according to ZatzNotFunny) to eligible consumers who are interested in getting a Roku device that’s up to snuff. Those users can find out more about that program by dropping an email to promohelp@roku.com.
